Maintaining your vehicle’s braking system is crucial for safety and optimal performance. One essential aspect of brake maintenance is regularly changing the brake fluid. Brake fluid is a hydraulic fluid that transmits pressure from the brake pedal to the brake calipers, allowing your car to stop effectively. Over time, brake fluid can absorb moisture, which lowers its boiling point and can lead to brake fade, a dangerous situation where your brakes become less responsive under heavy use.
How to Change Brake Fluid Honda Accord
This guide will walk you through the process of changing the brake fluid in your Honda Accord. While it’s generally recommended to have this service performed by a professional mechanic, it’s a relatively straightforward procedure that DIY enthusiasts can tackle with the right tools and knowledge.
Overview
Changing brake fluid involves bleeding the brake lines to remove old fluid and replace it with fresh fluid. This process requires careful attention to detail and proper bleeding techniques to ensure all air is removed from the system.
Before you begin, it’s important to gather the necessary tools and materials, consult your owner’s manual for specific instructions and safety precautions, and ensure you have a safe and well-ventilated workspace.
How To Change Brake Fluid Honda Accord
Maintaining your Honda Accord’s braking system is crucial for safety. One essential part of this maintenance is regularly changing the brake fluid. Brake fluid is a hydraulic fluid that transmits the force from your brake pedal to the brake calipers, ultimately stopping your vehicle. Over time, brake fluid absorbs moisture from the air, which can reduce its effectiveness and even lead to brake failure. Changing the brake fluid helps to ensure that your brakes operate optimally and reliably.
Why Change Brake Fluid?
Brake fluid is a vital component of your braking system, and its condition directly impacts your safety on the road. Here’s why it’s important to change the brake fluid regularly:
- Moisture Absorption: Brake fluid absorbs moisture from the air over time. This moisture lowers the fluid’s boiling point, making it more susceptible to vapor lock. Vapor lock occurs when the brake fluid boils under high heat, creating air bubbles in the lines, which reduces braking effectiveness.
- Corrosion: Moisture in the brake fluid can also lead to corrosion of metal components in the braking system, such as brake lines, calipers, and master cylinder.
- Reduced Performance: As brake fluid ages and absorbs moisture, its viscosity increases, making it harder for the brake pedal to apply pressure and resulting in a spongy or unresponsive brake feel.
Signs Your Brake Fluid Needs Changing
Regularly inspecting your brake fluid can help you identify potential issues before they become serious problems. Here are some signs that your brake fluid needs changing: (See Also: How Many Miles Before A Brake Job)
- Spongy Brake Pedal: If you feel a soft or spongy sensation when pressing the brake pedal, it could indicate air in the brake lines or degraded brake fluid.
- Low Brake Fluid Level: Check your brake fluid reservoir regularly. If the level is consistently low, it could indicate a leak in the system.
- Discoloration: Brake fluid should be clear or amber in color. If it appears dark brown or black, it’s a sign of contamination and needs to be changed.
- Metallic Smell: A burning or metallic smell coming from the brakes could indicate overheating, which can be caused by contaminated or low brake fluid.
Tools and Materials Needed
Before you begin, gather the necessary tools and materials. Having everything on hand will make the process smoother and more efficient.
- New brake fluid (DOT 3 or DOT 4, check your owner’s manual for the correct type)
- Brake fluid bleeder kit (includes bleeder screws, tubing, and a container)
- Wrench set
- Funnel
- Clean rags or paper towels
- Jack and jack stands (for raising the vehicle)
- Owner’s manual (for specific instructions and torque specifications)
Step-by-Step Guide
Follow these steps carefully to change the brake fluid in your Honda Accord:
1. Prepare the Vehicle
Park your Honda Accord on a level surface and engage the parking brake. Chock the rear wheels to prevent the vehicle from rolling.
2. Locate the Brake Fluid Reservoir
The brake fluid reservoir is usually located under the hood, near the firewall. It’s a clear plastic or metal container with a cap marked “Brake Fluid.”
3. Check the Fluid Level
With the engine off, carefully remove the brake fluid reservoir cap. Check the fluid level and note the amount.
4. Bleed the Brakes
Bleeding the brakes is a crucial step to remove any air bubbles from the system. This process involves opening a bleeder valve on each wheel cylinder or caliper, allowing brake fluid to flow out while simultaneously drawing fresh fluid into the lines.

- Identify the Bleeder Valves: The bleeder valves are typically located on the top or side of each wheel cylinder or caliper.
- Connect the Bleeder Kit: Attach the bleeder kit tubing to the bleeder valve on the rear wheel furthest from the master cylinder. Place the other end of the tubing into a clean container to collect the old brake fluid.
- Assist a Helper: Have a helper press the brake pedal several times while you carefully open the bleeder valve. This will allow air bubbles to escape and fresh fluid to flow into the line.
- Close the Valve: Once a steady stream of fluid flows from the bleeder valve, close it tightly.
- Repeat for Each Wheel: Repeat the bleeding process for each wheel, working your way towards the front of the vehicle.
5. Top Off the Brake Fluid Reservoir
After bleeding all four wheels, check the brake fluid level in the reservoir. Add new brake fluid as needed, making sure not to overfill.
6. Test the Brakes
Start your Honda Accord and test the brakes carefully. Apply the brakes gently at first, gradually increasing pressure. Listen for any unusual noises or feel for any spongy sensations. If everything feels normal, you’ve successfully changed the brake fluid.
Important Notes
Here are some additional points to keep in mind when changing brake fluid:
- Wear Safety Glasses: Brake fluid can be corrosive to skin and eyes. Always wear safety glasses when working with brake fluid.
- Work in a Well-Ventilated Area: Brake fluid vapors can be harmful. Work in a well-ventilated area or outdoors.
- Dispose of Brake Fluid Properly: Brake fluid is hazardous waste. Dispose of it properly at a designated recycling center.
- Torque Specifications: Refer to your owner’s manual for the correct torque specifications for the bleeder valves and other fasteners.
Recap
Changing the brake fluid in your Honda Accord is an essential maintenance task that can help ensure the safety and reliability of your braking system. By following the steps outlined in this guide, you can perform this task yourself and save money on labor costs. Remember to use the correct type of brake fluid, bleed the brakes properly, and dispose of the old fluid responsibly.
Frequently Asked Questions: Changing Brake Fluid on a Honda Accord
How often should I change my Honda Accord’s brake fluid?
Honda recommends changing the brake fluid every 2 years or 30,000 miles, whichever comes first. However, it’s a good idea to check your owner’s manual for specific recommendations for your model year.
What type of brake fluid should I use for my Honda Accord?
Consult your owner’s manual to determine the correct type of brake fluid for your Honda Accord. It will likely specify DOT 3 or DOT 4 fluid. Using the wrong type can damage your braking system. (See Also: How Hot To Brake Calipers Get)
